IMPROVEMENT IN STRAW-CUTTERS.

Specification forming part of Letters Patent No. 162,637, dated April27, 1875; application filed April 1'2, 1875.

To all whom it may concern:

Be it known that I, EDWARD W. FAWOETT, of Salem, county of Golumbianaand State of Ohio, have invented certain new and useful Improvements inFeed-Gutters, of which the following is a specification My inventionrelates to that class of feedcutters in which are two revolvingfeed-rollers and two or more curved knives with inclined edges, attachedto arms secured on a shaft parallel with and in front of the feed-rolls;and the nature of my invention consists in the construction of thegearing connecting the feed-rolls, in the devices for regulating thelength of the cut, and in the devices for maintaining the feed -rollersparallel with each other, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, whichforms a part of this specification, and in which- Figure l is a sideelevation of a feed-cutter embodying my invention. Fig. 2 is a view ofthe opposite side of the feed-cutter.

A represents the ordinary feed-box of this class of feed-cutters,provided at its front end with a metallic frame, B, in and on which theoperating parts are attached. a is the shaft carrying the cutting-kniveswithin the frame 13, said shaft having at one end the ily-wheel (J, andat the other end the pinion b, to gear with the crank-wheel D on the endof the driving-shaft d. E and G are the upper and lower feed rollers,respectively. The axle of the upper feed roller E has its bearings inracks f, connecting with and being controlled by segmental gears 6,attached to either end of a shaft, 1 whereby the upper roller, in itsmovement either up or down, is maintained parallel with the lower rollerG. On one side of the machine the axles or shafts of the feedrolls areprovided with gear-wheels h and k, respectively, on the axles of theupper and lower roller, which gear-wheels are so arranged that theymayoverlap or pass each other; or, in other words, one of these wheelsis farther out from the frame than the other. The gearwheels h k areconnected by two intermediate wheels, m and 'n, the wheel on havingsufficient width of face to admit of the other intermediate a, and itsconnecting feed-roll gear h, working and overlapping the other feedrollgear 75. The wide-faced pinion m is placed relative to the upperfeed-roll, so that when the upper feed-roll has attained one-half theelevation allowed, the axis of the pinion and that of the roll will bein the same horizontal plane, thereby allowing the roll to rise in aright line without materially affecting the meshof the gear. On theother side of the machine an arm or plate, I, is pivoted on the crank ordriving shaft d, which arm may be adjusted and held by means of a curvedslot at one end, and a bolt passing through the same and through theframe B. This arm or plate I has at its other end a stud carrying one ormore gear-wheels, J, which are operated by a pinion, p, on said shaft d,and the wheels J are engaged at will with corresponding wheels K on theshaft of the lower feedroller G. The wheels J-whether two or more-are ofdifferent diameter, and concentric with each other. The wheels K areconstructed in similar manner.

By swinging the lower end of the arm or plate I back, the wheels K onthe lower feedroll may so adjusted that the large wheel J on the arm mayengage thelarge one on the roll, the large one on the arm the small onthe roll, or the small one on the arm the large one on the roll, therebygiving 'three different speeds to the feed-rolls, enabling the operatorto adjust it to out either of three lengths at will.

By an increase of the gear-wheels on either the arm or on the feed-roll,or both, any desired 5 number of lengths of out may be obtained.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. In a teed-cutter, the combination of the upper yielding feed-rollerE, the racks ff,'

forming bearings for the axle of the roller, and the segmental gears 66attached to a shaft, i, and meshing with said racks, substantially asand for the purposes herein set forth.

2. The combination, with the feed-rollers E feed-roller Gr,substantially as and for the pun and G, the gear-wheels h 70, arrangedon their; poses herein set forth.

axles to overlap each other, and the intermediate wheels m and n, allconstructed substantially as and for the purposes herein set forth.

3. The combination, with the driving-shaft d and its pinion p, of theadjustable arm or plate I, carrying two or more concentric gearwheels,J, and two or more concentric gearwheels, K, secured on the journal ofthe lower In testimony that I claim the foregoing as my inventionIhereunt-o aflix my signature this 26th day of March, 1875.
